Description

Technical Field

[0001] This invention relates to the field of building block processing technology, and more specifically to a general-purpose material handling robot for building block injection molding production. Background Technology

[0002] In the field of building block production and processing, injection molding is the core process for building block manufacturing. As a key processing equipment, the production efficiency and degree of automation of building block injection molding machines directly determine the production capacity and quality of building block products. With the continuous enrichment of building block categories, the market demand for building blocks in terms of shape, size, and specifications is showing a diversified development trend. Correspondingly, the injection molds for building blocks also need to be customized according to the design requirements of different building block products. This leads to the need to frequently change injection molds during the production process to adapt to the batch processing needs of different types of building blocks or different accessories of the same type of building blocks.

[0003] Currently, in the automated production process of building block injection molding machines, the injection-molded building blocks need to be removed from the mold by a handling device (such as using a suction nozzle) and transferred to subsequent sorting, assembly or packaging processes. Among them, the suction nozzle handling device is the core component for realizing the automated handling of building blocks. Because the spacing between the molded building blocks varies significantly in different sizes of building block molds—for example, the array spacing and the spacing of the suction points for each block differ depending on the size and the assembly structure of the blocks—existing suction cup handling devices typically use a fixed nozzle layout design. This means that one robotic arm corresponds to only one specific spacing of the mold. However, this fixed layout has significant limitations: whenever production needs change and a different size building block mold is required, the spacing between the blocks in the new mold does not match the nozzle spacing of the original robotic arm, making stable suction and precise handling impossible. Therefore, a new suction cup handling device with the correct spacing must be installed simultaneously. During this replacement, the machine needs to be stopped, and operators must disassemble the old robotic arm and install and debug the new one. This process is cumbersome, time-consuming, and labor-intensive, significantly increasing downtime and interrupting the entire injection molding process, severely reducing handling efficiency and overall production efficiency.

[0004] Meanwhile, to accommodate various sizes of building block molds, companies need to stock multiple sets of handling devices with different nozzle spacings. This not only increases equipment procurement and warehousing costs but also requires additional manpower for the maintenance, debugging, and management of multiple robotic arms, further increasing the company's production and operating costs. Furthermore, frequent disassembly and installation of robotic arms can lead to wear and tear on equipment connections, affecting the positioning accuracy and lifespan of the robotic arms, thereby increasing the risk of equipment failure and indirectly impacting the handling stability and production continuity of building block products.

[0005] Therefore, given the production characteristics of block injection molding machines, developing a universal material handling robot that can flexibly adjust the nozzle position according to the spacing between blocks in different molds, adapt to various mold specifications, and is easy to adjust and accurately positioned has become an urgent technical problem to be solved in the current block injection molding production field. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a universal material handling robot for the injection molding production of building blocks.

[0029] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0030] See Figures 1-10 The universal material handling robot for block injection molding production of the present invention includes a frame 1, a conveying device 10 disposed on the frame 1, and a conveying drive mechanism 2 for driving the conveying device 10 to move along the X-axis, Y-axis and Z-axis.

[0031] The conveying device 10 includes a support 9, multiple sets of suction components 8 mounted on the support 9, a lateral spacing adjustment mechanism 4, and a longitudinal spacing adjustment mechanism 5.

[0032] The lateral spacing adjustment mechanism 4 is used to adjust the lateral spacing between two adjacent sets of suction components 8 in the multiple sets of suction components 8. The lateral spacing adjustment mechanism 4 includes multiple sets of lateral drive rods 403 and a lateral drive mechanism for driving the multiple sets of lateral drive rods 403 to move laterally. The multiple sets of lateral drive rods 403 are arranged laterally, and each set of lateral drive rods 403 extends longitudinally. The lateral drive mechanism includes a lateral motor 401 and a lateral lead screw transmission mechanism 402. The lateral motor 401 is mounted on the bracket 9. The lateral lead screw transmission mechanism 402 includes a lateral lead screw and a lateral lead screw nut that cooperates with the lateral lead screw. One end of the lateral drive rod 403 is connected to the lateral lead screw nut. The lateral lead screw is provided with multiple sets of first thread segments. The multiple sets of first thread segments are symmetrically arranged with a vertical plane perpendicular to the axis of the lateral lead screw as the center of symmetry. The helical directions of the first thread segments on both sides of the center of symmetry are opposite, and the pitch of each set of first thread segments on the same side of the center of symmetry is different.

[0033] The longitudinal spacing adjustment mechanism 5 is used to adjust the longitudinal spacing between two adjacent sets of suction components 8 in the multiple sets of suction components 8. The longitudinal spacing adjustment mechanism 5 includes multiple sets of longitudinal drive rods 503 and a longitudinal drive mechanism for driving the multiple sets of longitudinal drive rods 503 to make longitudinal movements. The multiple sets of longitudinal drive rods 503 are arranged longitudinally, and each set of longitudinal drive rods 503 extends laterally. The longitudinal drive mechanism includes a longitudinal motor 501 and a longitudinal screw transmission mechanism 502. The longitudinal motor 501 is mounted on the bracket 9. The longitudinal screw transmission mechanism 502 includes a longitudinal screw and a longitudinal screw nut that cooperates with the longitudinal screw. One end of the longitudinal drive rod 503 is connected to the longitudinal screw nut. The longitudinal screw is provided with multiple sets of second thread segments. The multiple sets of second thread segments are symmetrically arranged with a vertical plane perpendicular to the axis of the longitudinal screw as the center of symmetry. The helical directions of the second thread segments on both sides of the center of symmetry are opposite, and the pitch of each set of second thread segments on the same side of the center of symmetry is different.

[0034] The suction member 8 is installed at the intersection of the transverse drive rod 403 and the longitudinal drive rod 503, and the suction member 8 is provided with sliding holes that cooperate with the transverse drive rod 403 and the longitudinal drive rod 503 respectively.

[0035] In this embodiment, there are four sets of both the transverse drive rod 403 and the longitudinal drive rod 503, and correspondingly, there are sixteen sets of the suction member 8; there are two sets of the first thread segment and the second thread segment located on the same side of the center of symmetry of the transverse lead screw and the longitudinal lead screw; along the direction away from the center of symmetry, the pitch ratio between the two sets of first thread segments and the two sets of second thread segments is 1:3.

[0036] The purpose of the above settings is as follows: Figure 10As shown, since both the transverse and longitudinal lead screws are symmetrical about their own vertical planes, two sets of first thread segments or two sets of second thread segments are provided on the same side of the symmetry center, and the pitch ratio along the direction away from the symmetry center is 1:3; assuming that the two sets of first thread segments or two sets of second thread segments on the same side of the symmetry center are thread segments A1 / A2 and B1 / B2 respectively, and the pitch ratio of thread segments A1 / A2 and B1 / B2 is 1:3, the two sets of transverse drive rods 403 / longitudinal drive rods 5 on the corresponding thread segments... The moving distances of 03 are a and 3a respectively. Since the initial spacing of the two sets of transverse drive rods 403 / longitudinal drive rods 503 matches the spacing of the threaded segments; if the initial spacing of two adjacent sets of transverse drive rods 403 / longitudinal drive rods 503 is 3a, when the transverse drive rods 403 / longitudinal drive rods 503 on both sides of the center of symmetry move towards the center of symmetry, assuming the moving distance of the transverse drive rods 403 / longitudinal drive rods 503 located on threaded segments A1 and A2 is a, then the transverse drive rods 403 / longitudinal drive rods 503 located on threaded segments A1 and A2 will move a distance. The spacing between the moving rod 403 and the longitudinal driving rod 503 changes from 3a to a; the movement distance of the transverse driving rod 403 and the longitudinal driving rod 503 located on threaded sections B1 and B2 is 3a, so that the spacing between the transverse driving rod 403 and the longitudinal driving rod 503 located on threaded sections B1 and A1, and the spacing between the transverse driving rod 403 and the longitudinal driving rod 503 located on threaded sections B2 and A2, also changes from 3a to a; thus, the adjustment of two adjacent transverse driving rods 403 and the longitudinal driving rod 503 before and after adjustment... The spacing between the 03 remains constant, i.e., it is always 'a'. Similarly, when the two lateral drive rods 403 / longitudinal drive rods 503 move away from the center of symmetry, the spacing between the two adjacent sets of lateral drive rods 403 / longitudinal drive rods 503 changes from 3a to 5a. In both motion states, the spacing between the two adjacent sets of lateral drive rods 403 / longitudinal drive rods 503 remains uniform, thus achieving the accuracy and stability of the spacing adjustment. In addition, the above method is also applicable to other numbers of suction components 8.

[0037] See Figures 1-10 In the transverse lead screw, two adjacent sets of first threaded segments are connected by a coupling; in the longitudinal lead screw, two adjacent sets of second threaded segments are connected by a coupling. With the above arrangement, since the pitches of the two sets of first threaded segments and second threaded segments are different, the transverse drive rod 403 / longitudinal drive rod 503 can be installed on the corresponding threaded segments, and then the corresponding threaded segments can be connected by a coupling to form a complete transverse / longitudinal lead screw.

[0038] See Figures 1-10The other end of the transverse drive rod 403 is connected to the guide block in the transverse guide mechanism 6; the other end of the longitudinal drive rod 503 is connected to the guide block in the longitudinal guide mechanism 7; the transverse guide mechanism 6 and the longitudinal guide mechanism 7 are both mounted on the bracket 9 and are used to guide the transverse movement of the transverse drive rod 403 and the longitudinal movement of the longitudinal drive rod 503; in this embodiment, the transverse guide mechanism 6 and the longitudinal guide mechanism 7 are both constructed using a combination of slider and slide rail, or a combination of slide rod and slider.

[0039] See Figures 1-10The suction component 8 includes a housing 801, a suction nozzle 803 disposed on the housing 801, and an axial drive assembly for driving the suction nozzle 803 to move along the axial direction of the housing 801. The axial drive assembly includes a gas communication pipe 804 and a linear drive component 802. The housing 801 is provided with a guide groove that mates with the linear drive component 802. The suction nozzle 803 is mounted on the air outlet 8042 of the gas communication pipe 804. The housing 801 is provided with an air inlet, which communicates with a negative pressure pipe 805. The side wall of the gas communication pipe 804 is provided with an air inlet 804 that mates with the air inlet. 1; The linear drive 802 drives the gas connecting pipe 804 to move axially, so as to connect or disconnect the air inlet on the housing 801 with the air inlet 8041 of the gas connecting pipe 804; The linear drive 802 is an electromagnet and can be reset by a spring. Alternatively, a small linear motor can be used; With the above settings, the number of suction components 8 can be selected to work according to the number of building block mold cavities, while the remaining suction components 8 are in a non-working state. This ensures that the suction force of the suction components 8 that need to work in the conveying device 10 reaches a preset threshold, while the non-working suction components 8 are disconnected from the negative pressure pipe 805. Because the molds used for producing different building blocks have different cavity spacing and numbers, the above settings allow for the selection of the appropriate suction unit 8 to work according to actual conditions, adapting to different types of building block molds and further improving production flexibility. The specific action is as follows: the linear drive unit 802 drives the gas connecting pipe 804 to move axially inward, causing the air inlet 8041 on the gas connecting pipe 804 to disconnect from the air inlet on the housing 801 of the suction unit 8, thereby cutting off the connection between the inactive suction unit 8 and the negative pressure pipe 805. At the same time, because the linear drive component 802 drives the gas connecting pipe component 804 and the suction nozzle 803 on it to move axially inward synchronously, the height of the non-working suction nozzle 803 can be slightly higher than that of the working suction nozzle 803. In this way, on the one hand, it can prevent the non-working suction nozzle 803 from contacting the building block mold, preventing wear on the building block mold or suction nozzle 803 and interference with normal material picking; on the other hand, it can prevent the non-working suction nozzle 803 from diverting negative pressure, thereby ensuring that the working suction nozzle 803 can obtain sufficient suction force to accurately and stably pick up the building blocks in the mold cavity of the building block mold.

[0040] See Figures 1-10 The outer contour of the gas connecting pipe 804 has a polygonal cross-section, and correspondingly, the cross-section of the guide groove is also polygonal. Through the above arrangement, the gas connecting pipe 804 can be prevented from rotating in the guide groove, thereby ensuring that the air inlet 8041 in the gas connecting pipe 804 and the air inlet in the housing 801 can be precisely matched.

[0041] See Figures 1-10 The transport drive mechanism 2 can be implemented using an existing transport drive mechanism 2, thereby driving the transport device 10 to move along the X-axis, Y-axis, and Z-axis. For example, it can be implemented using a combination of a motor and a lead screw drive mechanism, or a combination of a motor and a gear and rack mechanism. At the same time, the transport drive mechanism 2 also includes a swing drive mechanism 3 for driving the transport device 10 to swing around the X-axis, for example, by directly using a motor drive, or by combining a motor and a gear and rack mechanism. With the above settings, the transport device can be driven to complete the transport and transfer of building blocks, so as to adapt to different types of building block injection molding machines.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
